Texture evolution of an Al-8Zn alloy during ECAP and post-ECAP isothermal annealing [PDF]

Materials Characterization, 2019
Abstract In this work, the texture evolution of an Al-8 wt% Zn alloy during equal channel angular pressing (ECAP) and post-ECAP isothermal annealing was systematically investigated by electron backscatter diffraction (EBSD). Special attention is paid to the influence of static recovery and recrystallization on ECAP texture.

Integrated Assessment of Wall Shear Stress‐Related Hemodynamic Parameters in Abdominal Aortic Aneurysms: A Retrospective Cross‐Sectional Study on Ruptured Cases

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 3, March 2026.
Abdominal aortic aneurysms (AAAs) pose a substantial threat to public health due to their risk of rupture, which can be life‐threatening. Current clinical practice relies primarily on AAA diameter and growth rate as indicators to determine if surgical treatment is imperative. This study investigates the integration of WSS‐related hemodynamic parameters,

Advancing Severe Plastic Deformation for Tubular Samples: Systematic Review and Machine Learning Optimization

MetalMat, Volume 3, Issue 1, March 2026.
This review highlights recent advancements in Severe Plastic Deformation (SPD) techniques tailored for tubular samples. The mechanisms of processing are critically discussed with emphasis on microstructural control and the governing process parameters that enable refinement to ultrafine‐ and nano‐grained structures. Comparative insights into equivalent
